ABSTRACT:
A magnetic storage device comprising a rigid apertured cartridge containing a flexible magnetic disk and a Bernoulli surface is disclosed. The cartridge contains a reference surface which is integral with the Bernoulli surface and serves to align and flatten the Bernoulli surface when the cartridge is inserted into a disk drive. The cartridge is configured such that the flexible magnetic disk is maintained in operative association with the Bernoulli surface. The aperture of the cartridge serves as an entry point for the motor spindle and transducer of the disk drive. The cartridge is partially enclosed by a slidable shutter which protects the Bernoulli surface and flexible disk when the cartridge is not in use.
